豆腐是餐桌上的常客,不仅吃法是多种多样的，营养也是很丰富，十分受人们喜爱。

Tofu is a frequent customer on the table. Not only does it have a variety of ways to eat, but it is also rich in nutrition, and it is very popular.

我们该怎样选购豆腐呢？How should we buy tofu?

能卖，尽量选择正规渠道购买，选购时需要特别注意考虑其是否存在安全性风险，比如豆腐发酸或酸化，说明可能发生了腐败变质等。

Can be sold, try to choose formal channels to buy, you need to pay special attention to whether there are safety risks when purchasing, such as sour or acidified tofu, indicating that corruption may have occurred.

人体容易出现结石的部位主要在消化系统和泌尿系统，如出现胆结石和肾结石。网上传言中主要说的是豆腐吃多了得肾结石。

The human body is prone to stones in the digestive system and urinary system, such as gallstones and kidney stones. The rumors on the Internet mainly say that kidney stones are caused by eating too much tofu.

医学上肾结石的形成，一般是由于尿液中的盐类过饱和造成结晶析出，同时尿液中抑制结晶形成的物质减少，久而久之就形成结石。

In medicine, the formation of kidney stones is generally due to the precipitation of crystals due to the supersaturation of salts in the urine, and at the same time the reduction of substances that inhibit the formation of crystals in the urine, and stones will form over time.

最为常见的肾结石是含钙结石，还有一些是尿酸过高引起的尿酸结石，以及细菌感染引发的感染性结石等。膳食中的某些营养成分确实可以增加患结石的风险，如钙、草酸和嘌呤等，但主要因素是不健康的饮食方式和习惯，如膳食结构单一、饮水过少等。

The most common kidney stones are calcium-containing stones, some are uric acid stones caused by high uric acid, and infectious stones caused by bacterial infections. Certain nutrients in the diet can indeed increase the risk of stones, such as calcium, oxalic acid and purines, but the main factors are unhealthy eating styles and habits, such as a simple diet and too little drinking water.

健康人多吃一点豆腐是没事，但对于痛风、高尿酸血症和肾石病患者来说，一定程度上可以考虑限制豆腐等豆制品的摄入量。

It is fine for healthy people to eat more tofu, but for patients with gout, hyperuricemia and kidney stone disease, to a certain extent, consider limiting the intake of tofu and other soy products.

从降低风险考虑，可以选择鸡蛋、牛奶那些更为安全的食物作为蛋白质的来源。

From the perspective of reducing risk, you can choose safer foods such as eggs and milk as the source of protein.

豆腐的加工关键在于凝固成型环节：

The key to tofu processing lies in the solidification process:

传统的豆腐成型方式是使用盐类的凝固剂，比如用石膏（主要成分硫酸钙）或卤水（主要成分氯化镁、氯化钙、硫酸镁）进行点卤成型；

The traditional way to shape tofu is to use salt coagulant, such as gypsum (main component calcium sulfate) or brine (main component magnesium chloride, calcium chloride, magnesium sulfate) for point brine molding;

而现代主要用酸类凝固剂进行豆腐的成型，比如葡萄糖酸（食品工业主要用葡萄糖酸内酯）等。

In modern times, acid coagulants are mainly used for tofu forming, such as gluconic acid (gluconolactone is mainly used in the food industry).

因此，我们在选购豆腐的时候可以参考自身需求，追求营养选卤水豆腐，追求口感选内酯豆腐。

Therefore, we can refer to our own needs when buying tofu, choose brine tofu for nutrition, and lactone tofu for taste.

豆腐的热量不算太低，而且不同类型的豆腐热量差异也比较大。比如，按照我国食物成分表，每100克内酯豆腐、南豆腐、北豆腐的热量分别为50kcal、87kcal和116kcal，而同样重量的米饭为116kcal。

The calories of tofu are not too low, and different types of tofu have relatively large differences in calories. For example, according to our country's food composition table, the calories per 100 grams of lactone tofu, southern tofu, and northern tofu are 50kcal, 87kcal and 116kcal, respectively, while the same weight of rice is 116kcal.
